ACRYLIC ACID/ACRYLAMIDOMETHYL PROPANE SULFONIC ACID COPOLYMER
Description
Acrylic Acid/Acrylamidomethyl Propane Sulfonic Acid Copolymer is a multifunctional synthetic ingredient widely used in skincare and cosmetic formulations. This copolymer is composed of two distinct monomers: acrylic acid and acrylamidomethyl propane sulfonic acid, which combine to create a versatile polymer with unique properties. Its primary functions include acting as a film-forming agent, viscosity controller, and emulsion stabilizer.
In skincare products, this copolymer enhances texture and improves the overall feel of formulations on the skin. It forms a lightweight, non-occlusive film that helps to retain moisture and protect the skin barrier. The ingredient's ability to control viscosity allows for the creation of various product consistencies, from lightweight serums to rich creams. As an emulsion stabilizer, it helps maintain the integrity of formulations containing both oil and water components.
The copolymer is particularly effective in sun care products, where it can improve the water resistance of sunscreens and enhance their durability. It is generally well-tolerated by most skin types and is considered safe for use in cosmetic formulations at recommended concentrations. However, as with any synthetic ingredient, patch testing is advisable for individuals with sensitive skin or a history of allergic reactions.
